Answer:
Option C is correct.
She is not correct as she use the wrong y intercepts when graphing the equations.
Step-by-step explanation:
Given the system of equations:
.....[1]
. .....[2]
equate these two equations we get;

Add 5 to both sides we get;

Add 2x to both sides we have;

Multiply both sides by 3 we get;
8x = 24
Divide both sides by 8 we get;
x = 3
Substitute the value of x in [2] we have;
y = -2(3)+3 = -6+3
Simplify:
y = -3
Therefore, the correct solution for this given system of equation is (3, -3)
You can see the graph of these equations below.
Answer:
72178.4777
Step-by-step explanation:
Answer:
choice 3) acute and equilateral
Step-by-step explanation:
Distribute the 3 to 4m and 6. this makes 12m-18=12
now add 18 to both sides.
12m=30
now divide by 12
m=30/12
Answer:
x = 0 and x = 1
Step-by-step explanation:
Given that,
A football is kicked into the air. The height of the football can be modeled by the equation :

Where
h is the height reached by the ball after x seconds
When it touches the ground, h = 0
So,

So, it will touch the ground at x = 0 and x = 1 seconds.
